chore(loop-tick-history): §33 substrate-primitive zero-violations milestone tick

[AceHack]

Summary

Substantive tick row marking B-0036 Sub-task 1 completion: §33 archive header lint progression 36 → 0 violations on main.

Milestone

The full §33-archive-header substrate-primitive lifecycle from recurring-review-finding-pattern to operational-CI-enforcement landed across this autonomous segment:

• Lint shipped: PR feat(hygiene): tools/hygiene/check-archive-header-section33.sh — §33 archive header lint + B-0036 backfill backlog #571 (label-presence + courier-ferry detection)
• Lint enhanced: PR feat(check-archive-header-section33): validate Operational-status enum value (Codex P2 follow-up) #575 (enum-value validation)
• 6-PR backfill chain: backfill(B-0036 partial): §33 archive headers on 7 Amara-courier-ferry research docs #572 / backfill(B-0036 partial-2): bold-strip §33 labels on 6 Shape A pre-existing docs + line-20 calibration finding #573 / backfill(B-0036 partial-3): normalize Operational-status enum-strict on 6 Shape A pre-existing docs #576 / backfill(B-0036 partial-4): full §33 headers on 6 Shape B pre-existing courier-ferry docs (lint 9 → 3) #577 / backfill(B-0036 partial-5): bold-strip + enum-strict on aminata-threat-model-5th-ferry doc #578 / backfill(B-0036 partial-6): resolve line-20 calibration via §33 block compression on 3 docs #579
• Lint progression: 36 → 19 → 12 → 9 → 4 → 1 → 0
• CI wire (B-0036 Sub-task 2): PR feat(gate.yml): wire check-archive-header-section33.sh as enforcing CI lint (B-0036 Sub-task 2) #580 (in flight, auto-merge enabled)

Three observations

1. Otto-346 substrate-primitive pattern proven end-to-end on a single discipline within one session: discipline lacks automation → recurring review finding → tool ships → review tightens acceptance criteria across multiple iterations → backfill clears retroactive debt → CI wire makes future violations impossible
2. Discipline-correctness over rule-relaxation: B-0036 calibration tension chose path (a) compression over (b) relax-window or (c) amend-spec, preserving GOVERNANCE.md §33 spec as written
3. Autonomous-loop sustained substantive output for the full hour-long quiet window per Otto-322/325/326/328 self-directed-action discipline

Test plan

• tick-history check-order passes (134 rows, non-decreasing)
• Single substantive row, not minimal heartbeat
• Captures the substrate-primitive-lifecycle observation cleanly
• Notes Aaron's return + good-job acknowledgment

Pull request overview

Records a substantive loop-tick-history milestone capturing completion of the §33 archive-header backfill chain reaching 0 violations on main, and noting the follow-on CI wiring PR in flight.

Changes:

• Appends a new tick-history row documenting the §33 lint/backfill lifecycle completion and the 36 → 0 progression.
• Captures the “substrate-primitive” observation/lifecycle narrative for future traceability.
